How to build a simple VCL Application to view Zoho Creator データ in RAD Studio using the CData ODBC Driver for Zoho Creator.
最終更新日:2023-06-12Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Zoho Creator, you gain access to live Zoho Creator データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Zoho Creator データ. This article will walk through connecting to Zoho Creator and creating a simple VCL application with the Form Designer.
Create a Connection to Zoho Creator データ
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Zoho Creator 接続プロパティの取得・設定方法
Zoho Creator に接続するには、Region をサーバーURL のトップレベルドメイン(TLD)に設定します。
Zoho Creator への認証
Zoho Creator は、データに接続する2つの方法を提供します。
- デスクトップ経由で自分のローカルデータに接続する場合(非ブラウザ接続)は、CData が提供する組み込みOAuth アプリケーションを使用します。
- ネットワーク経由で共有データに接続する場合(ブラウザ接続)は、カスタムOAuth アプリケーションを使用します。
- デスクトップ:ユーザーのローカルマシン上でのサーバーへの接続で、テストやプロトタイピングによく使用されます。埋め込みOAuth またはカスタムOAuth で認証されます。
- Web:共有ウェブサイト経由でデータにアクセスします。カスタムOAuth でのみ認証されます。
- ヘッドレスサーバー:他のコンピュータやそのユーザーにサービスを提供する専用コンピュータで、モニタやキーボードなしで動作するように構成されています。埋め込みOAuth またはカスタムOAuth で認証されます。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Zoho Creator データ.
- In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
- Right-click the ODBC Data Source node in the Data Explorer.
- Click Add New Connection.
- Enter a name for the connection.
- In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Zoho Creator.

Create VCL Applications with Connectivity to Zoho Creator データ
Follow the procedure below to start executing queries to Zoho Creator データ from a simple VCL application that displays the results of a query in a grid.
-
Drop a TFDConnection component onto the form and set the following properties:
- ConnectionDefName: Select the FireDAC connection to Zoho Creator データ.
- Connected: Select True from the menu and, in the dialog that appears, enter your credentials.
-
Drop a TFDQuery component onto the form and set the properties below:
- Connection: Set this property to the TFDConnection component, if this component is not already specified.
SQL: Click the button in the SQL property and enter a query. For example:
SELECT ID, Leave_Type FROM Leave_Types WHERE Leave_Type = 'Sick'
- Active: Set this property to true.
Drop a TDataSource component onto the form and set the following property:
- DataSet: In the menu for this property, select the name of the TFDQuery component.
-
Drop a TDBGrid control onto the form and set the following property:
- DataSource: Select the name of the TDataSource.
- Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
